Agentic sales enrichment spreadsheet. Backed by Y Combinator.
About the role
We’re hiring a Founding Engineer to own major slices of the product and infrastructure alongside the founders. This is a high-ownership, high-trust role: you’ll ship user-facing features, harden core systems, and help define how we scale—not just close tickets.
What they're looking for
- Strong TypeScript and comfort owning features full-stack (React/Next patterns, server routes, database design)
- Bias to ship : you break work into milestones, default to simple designs, and iterate with real users
- Systems thinking : you care about idempotency, failure modes, and operational clarity—not only happy paths
- Product sense : you ask who is this for and what must be true for them to trust it? especially around data quality and AI outputs
- Bonus (not required): experience with Postgres at scale , Stripe billing , queue/workflow systems , LLM app patterns , or B2B data / GTM tools
More about this role
Orange Slice helps revenue teams prospect, enrich, qualify, and automate GTM work with AI . Customers use it to turn messy intent and company context into actionable lists, enriched records, and workflows —from firmographics and contact verification to web research, social signals, and outreach drafting. The product spans a polished web experience (including spreadsheet-like execution and an AI agent) and tooling for builders who want the same capabilities in code or in Claude Code via a single install path.
We sit at the intersection of B2B data , LLMs , and workflow automation —where reliability, cost control, and great UX matter as much as model quality.
